LUG TIRE

摘要

A noiseless lug tire which runs at a high speed under a heavy load and which satisfies the following conditions. (1) A ratio Wg/Wl is equal to or smaller than 1.0. (2) Each transverse groove for delimiting lugs is not inclined toward an opening of the transverse groove at the kickout side of each lug. (3) Each transverse groove is inclined toward the opening at the stepin side of each lug at an angle of at most 22 DEG . (4) Each portion of a center line of the transverse groove in a substantially total region of a length L of the transverse groove is inclined with respect to the meridian line of the tire at an angle within a range from at most 15 DEG measured in a direction opposite to the inclination direction of the transverse groove as a whole to at most 60 DEG measured in the same direction as the inclination direction of the transverse groove as a whole.
